I have some one off pdf java code in which I'm using Itext-1.4.1. I used
a number of examples and code found on this list and elsewhere - so if it
looks familiar it probably is.
The code performs the following:
for each file it finds in a directory it reads the file and fields and
replaces any fields named *.1 with *.2 (2..5) then saves the new file
naming the new file oldFileName.2.pdf - it then concats itself to the end
of the oldFileName.pdf. I do this 5 times up through oldFileName.5.pdf
(which is 5 copies of oldFileName.pdf with renamed fields on each.
It also contains fields that it doesn't rename and I want these to be the
same on each page in the new file.
The problem is any fields on file1 that aren't renamed will not copy over
correcty to file2 - they appear correct in the form tool in acrobat until
I open up the field - it doesn't have a name and will blow up when I try
to merge an fdf with it.
I'm attempting to include the code here... Thanks in advance for any
suggestions.
